I assume you'll be shooting 35 or 40g bullets with the 1:12 twist?

My 1-12 twist barrel loves 55grain...
Nice rifle, great upper.. I almost built one, but then got a really good deal on an AR––57 upper {$500 never fired with 10 50 round ps90 mags}, I will do one in the future...

Love the looks of the OPS-4, especially on a precision rig. Now if LAR will only produce the 308 and piston versions that they promised were going to be out a year ago.

52 and 53 grains. Very good twist rate for those.
